MoreBeer.com, a leader in the homebrew equipment space has a monthly sale that they announce on their site and via a podcast each month.  I just listened to their podcast via itunes and they have some great sales going on.  Additionally, they are running a contest from not until the end of December to give away one of their brand new Pressurizable Conical Fermenters.  Check out the details at MoreBeer Fall Sales.
